I'm a little closer now...
After reading that the message type is toggled on whether or not the
content-length header is included,
http://activemq.apache.org/stomp.html, I dug in to the stomp gem and
found that it is hard coded to always send the content-length header.
def _transmit(s, command, headers={}, body='')
@transmit_semaphore.synchronize do
s.puts command
headers.each {|k,v| s.puts "#{k}:#{v}" }
s.puts "content-length: #{body.length}"
s.puts "content-type: text/plain; charset=UTF-8"
s.puts
s.write body
s.write "\0"
end
After removing the content-length header, it seems to work as
expected. Would the right way to implement this be to use camel to
convert the message type for messages I want to consume over the web?
Or for this specific case would it be appropriate to implement a case
in MessageListenerServlet to handle BytesMessages?
